the following files (reported by tlmgr check) have two different instances in the runtime. i've already contacted all the authors once with various resulting promises to eventually fix it, but nothing has ever happened. i'm too discouraged about it to do it again. pushing the bug report here in hopes that someone else will eventually come across it and take it on.

(At present, I filter these out from the cron job so I don't have to see them every day; at least no new ones should creep in.)
